Worm feeding on algae, light micrograph
Worm feeding on algae. Light micrograph of an microscopic annelid worm (subclass Oligochaeta, upper left) feeding on green algae

Philodina rotifer, light micrograph
Philodina rotifer. Light micrograph of a Philodina roseola rotifers head, showing its mouthparts (left). Rotifers are microscopic aquatic animals that are related to roundworms

Heartworms, light micrograph
Heartworms. Light micrograph of three Dirofilaria immitis heartworms. During the adult stage of their life cycle, these nematode worms live in the right ventricle of animal hearts

Threadworm, light micrograph
Threadworm. Light micrograph of a female Enterobius vermicularis threadworm. Threadworms are nematode worms that parasitise the large intestine and caecum of many animals

Ascaris roundworm, light micrograph

C. elegans mutant worm, light micrograph
C. elegans worm. Differential interference contrast micrograph of a rolling mutant Caenorhabditis elegans worm. Rolling mutants move in a circular, rather then the normal sinusoidal, path

C. elegans worm, light micrograph
C. elegans worm. Differential interference contrast micrograph of a Caenorhabditis elegans larva. The head is at bottom left

Common earthworm (Lumbricus terrestris). This is an annelid worm that inhabits soil, feeding on organic material. Earthworms are highly beneficial as their movement aerates the soil

Rotifer foot, light micrograph. Rotifers are microscopic aquatic animals that are related to roundworms. The hair-like cilia surrounding the rotifers mouth (right) are used to trap food particles

Caenorhabditis elegans, micrograph
Caenorhabditis elegans. Fluorescence micrograph of the transparent nematode (roundworm) worm Caenorhabditis elegans. A fluorescence microscope is an optical microscope that uses fluorescence

Threadworm, SEM
Threadworm. Coloured scanning electron micrograph (SEM) of the head of a thread worm (Enterobius sp.). This is a nematode worm that is a parasite of the small intestines of numerous animals

Lepadella rotifer, light micrograph
Rotifer. Differential interference contrast micrograph of a Lepadella sp. rotifer. Rotifers are microscopic aquatic animals that are related to roundworms

Marine nematode worm, light micrograph
Marine nematode worm. Differential interference contrast micrograph of a marine nematode worm found in the North Sea. Magnification: x300 when printed at 10 centimetres wide

The round worm, also known as the nematode worm, is a fascinating creature that comes in various forms. One of the most well-known species is C. Elegans, which has been extensively studied in scientific research. Through light micrographs and scanning electron microscopy (SEM), we can observe the intricate details of these worms. In one image captured by SEM, we see a nematode worm with its elongated body and distinct features. These parasitic nematodes are notorious for causing diseases in humans and animals alike. Their ability to adapt and survive in different environments is truly remarkable. Another light micrograph showcases roundworm germ cells under magnification. The delicate structures within these cells highlight their importance in reproduction and genetic diversity. Similarly, another image reveals more roundworm germ cells, emphasizing their significance in the life cycle of these organisms. Moving on to C. Elegans specifically, an LM image provides us with a closer look at this model organism's anatomy. Its transparent body allows researchers to easily study its internal organs and developmental processes. Artwork depicting Ascaris sp. , a type of nematode worm found in the human intestine, gives us an artistic representation of these creatures' presence within our bodies. This serves as a reminder that not all interactions between humans and worms are beneficial or harmless. Brugia malayi is another example of a parasitic nematode worm that causes human filariasis - a debilitating disease affecting millions worldwide. A light micrograph captures its structure, highlighting the need for further research into prevention methods and treatments for such infections. Lastly, an SEM image shows false coloration applied to showcase a nematode worm found on peat samples – demonstrating how diverse these organisms can be even when living within seemingly inhospitable environments.
